DETAILED DESCRIPTION

[0028] The embodiments of the present application will be further described below in conjunction with the drawings and examples. The detailed description of the following examples and drawings are used to exemplarily illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described examples.

[0029] In order to better understand the present application, the present application will be further described below in conjunction with the drawings and embodiments:

[0030] Referring to Figures 1-5 The embodiment of the present application provides a supporting foot opening device, which comprises a main rod 1, a connecting rod member 3 and a locking mechanism 4.

[0031] Specifically, the main rod 1 comprises a main body part 11 and a base part 13, the base part 13 is installed at the bottom of the main body part 11, and the base part 13 and the main body part 11 are detachably connected. The detachable connection mode includes but is not limited to threaded connection and buckle connection.

[0032] In the embodiment, the main body part 11 is provided with a sliding groove 111 and an elastic element 2 arranged in the sliding groove 111, the elastic element 2 is always in a compressed state in the sliding groove 111, when the locking mechanism 4 is in a locked state, the compression amount (the distance of the elastic element 2 compressed from the original length) of the elastic element 2 is X1, when the locking mechanism 4 is in an unlocked state, the compression amount (the distance of the elastic element 2 compressed from the original length) of the elastic element 2 is X2, wherein X1 is greater than X2.

[0033] Specifically, the elastic element 2 includes but is not limited to spring, composite elastomer and the like.

[0034] Referring to Figures 3-4As shown, the link member 3 is provided with a first rotating shaft 31 at one end, and the first rotating shaft 31 is connected with the support member 6. The link member 3 is provided with a second rotating shaft 32 at the other end, and the second rotating shaft 32 is at least partially located in the sliding groove 111. The elastic element 2 is in abutment with the second rotating shaft 32 at one end, and in abutment with the base portion 13 at the other end. The locking mechanism 4 has a locked state and an unlocked state. When the locking mechanism 4 is in the locked state, the locking mechanism 4 clamps the plurality of support members 6 so that the plurality of support members 6 are folded to the outer wall of the main body portion 11. When the locking mechanism 4 is in the unlocked state, the elastic element 2 releases the elastic potential energy to drive the second rotating shaft 32 to move in the sliding groove 111 to promote the support member 6 to pivot and expand. In this way, the linear motion of the second rotating shaft 32 in the sliding groove 111 (driven by the elastic element 2) is converted into the rotary motion of the support member 6 by the link member 3, so that the support member 6 is realized to pivot and expand. At the same time, the movable sleeve 5 moves from one end of the main body portion 11 to the direction close to the base portion 13. By converting the linear driving force into rotary motion, the energy loss is reduced, and the expansion speed of the support member 6 can be effectively improved.

[0035] Specifically, when folded, the external force pushes the support member 6 to fold, and the reverse rotation of the first rotating shaft 31 forces the second rotating shaft 32 to compress the elastic element 2 through the link member 3, so as to realize the storage of elastic energy. When the support member 6 is folded to closely fit the outer wall of the main body portion 11, the locking mechanism 4 clamps the plurality of support members 6 so that the plurality of support members 6 are folded to the outer wall of the main body portion 11, thereby significantly reducing the overall volume of the support foot unfolding device, facilitating carrying or storage.

[0036] When unfolded, the elastic element 2 pushes the second rotating shaft 32 to slide along the sliding groove 111, and drives the support member 6 to unfold through the link member 3.

[0037] In this embodiment, the sliding groove 111 provides a linear motion track for the second rotating shaft 32, limits the movement direction, and can ensure that the energy of the elastic element 2 is released along a fixed path, avoiding the transverse deviation of the elastic element 2 to cause energy waste or structural wear of the elastic element 2.

[0038] In the embodiment, the movable sleeve 5 is sleeved on the outer wall of the main body 11, and the movable sleeve 5 is provided with a rotating shaft groove. One end of the supporting member 6 is provided with a third rotating shaft 51, the third rotating shaft 51 is located in the rotating shaft groove and connected with the movable sleeve 5, and the third rotating shaft 51 rotates in the rotating shaft groove when the supporting member 6 is unfolded. In this way, the longitudinal displacement freedom of the supporting member 6 is provided by the sliding of the movable sleeve 5. When the third rotating shaft 51 rotates in the rotating shaft groove, the movable sleeve 5 can be adaptively adjusted in position, so that the rigid interference between the supporting member 6 and the main rod 1 is avoided when the supporting member 6 is unfolded. Specifically, the plurality of supporting members 6 are linked by the same movable sleeve 5, and the movable sleeve 5 is installed on the outer wall of the main body 11 in a sleeved manner, so that the unfolding angle and speed of each supporting member 6 can be ensured to be synchronous.

[0039] Referring to Figure 5 As shown in the figure, the locking mechanism 4 includes a button 41 and a fixed hook 42 connected with the button 41. The fixed hook 42 includes a fixed part 421 and a plurality of cantilever arms 422 extending outward from the fixed part 421. The end of each cantilever arm 422 is provided with a hook structure, and the hook structure is clamped with the supporting member 6 to make the supporting member 6 fold on the outer wall of the main body 11.

[0040] Specifically, the main body 11 is provided with a notch 112 matched with the cantilever arm 422. When the button 41 is triggered, the cantilever arm 422 can move in the notch 112 by a predetermined distance, so that the locking mechanism 4 is switched from the locked state to the unlocked state.

[0041] In the embodiment, a part of the connecting rod member 3 is arranged in the notch 112. When the button 41 is pressed, the button 41 and the fixed hook 42 move inwardly of the main body 11 by a predetermined depth, the cantilever arm 422 moves from the opening end to the closing end of the notch 112, so that the cantilever arm 422 and the supporting member 6 are released from the locked state. When the supporting member 6 is pushed to fold, the elastic element 2 pushes the second rotating shaft 32 to slide along the sliding groove 111 towards the base 13, and the connecting rod member 3 in the notch 112 is lifted, so as to push the cantilever arm 422 to move from the closing end to the opening end of the notch 112. When the supporting member 6 is folded to closely adhere to the outer wall of the main body 11, the cantilever arm 422 moves to a predetermined position, so as to be clamped with the supporting member 6 to achieve locking.

[0042] Referring to Figure 4 As shown in the figure, the base 13 is provided with a protruding section 131, and at least a part of the protruding section 131 is arranged in the elastic element 2. In the embodiment, the protruding section 131 serves as an inner guide shaft of the elastic element 2, which can limit the lateral deviation of the elastic element 2, so as to ensure that the elastic element 2 is only compressed or stretched in the axial direction, and avoid energy loss or structural failure caused by lateral bending.

[0043] Referring to Figure 5As shown, the base portion 13 is provided with a mounting hole 132 penetrating through the thickness of the base portion 13, and the button 41 is at least partially arranged in the mounting hole 132. Specifically, the base portion 11 is provided with a stop seat 12 at the upper end, and the stop seat 12 is formed with an annular table surface, which abuts against the upper end of the movable sleeve 5 when the support member 6 is folded on the outer wall of the base portion 11.
